Yup.  Taking an example from current glibc sources: include/libc-symbols.h

#   define __make_section_unallocated(section_string)   \
  asm(".section " section_string "; .previous");

Here, the ".previous" is treated as a comment by hppa gas.  I sent a patch
to Ulrich Drepper for this a long time ago, but it hasn't gone in (and in
case Ulrich is reading this, there's no pressing need for it to go in yet
as hppa-linux glibc needs quite a bit of work)

Yes, that would be reasonable.  I just picked `-c' as an unused letter.
